for the love of learning: Reduced to Numbers

for the love of learning: Reduced to Numbers: "Last year, teachers in Los Angeles suffered under the LA Times printing of teacher evaluations based on standardized test scores.

This year, New York teachers are the target of a naming and shaming operation that took place when the New York media published evaluations that ranked teachers by their students' standardized test scores.

There's a lot wrong with all this and Diane Ravitch aptly explains how reducing the quality of a teacher to a score and then making this unreliable and invalid data public is nothing more than a ploy to undermine public confidence in public education.

The problem here isn't just that these teacher evaluations and rankings were made public -- although making them public certainly does make things worse -- the real problem here is that the complex work of teaching is being reduced to a number at all.

Teacher evaluations via test scores are prone to such error that they are not valid or reliable regardless of whether they are public or private. "
